Title: Removing carbon from solid surfaces
IPC: C03C17/25
Filed: 1982-11-22
Abstract: A C layer is removed from a solid surface, pref. a metal or ceramic, by (a) contacting with a gaseous fluid contg. SO3; pref. under anhydrous conditions; (b) rinsing, pref. with water; and (c) pref. contacting the surface with a passivating soln., esp. contg. a chelating agent. Alternatively, rinsing may be by contacting with a passivating soln. The gaseous fluid is pref. gaseous SO3, or is nonreactive with SO3. - The process effectively removes C, e.g. formed on steel plates by lubricant residue, avoiding interference with subsequent processing. Most of the C may be removed in a few seconds contact. Metal surfaces may be left activated, and corrosion is avoided by passivating.

Abstract: PCT No. PCT/GB84/00306 Sec. 371 Date Jan. 21, 1985 Sec. 102(e) Date Jan. 21, 1985 PCT Filed Sep. 3, 1984 PCT Pub. No. WO85/01086 PCT Pub. Date Mar. 14, 1985.A gerotor pump is arranged for unidirectional flow irrespective of direction of rotation of the pump by arranging for displacement of the axis of eccentricity of the annulus and rotor upon drive reversal, the annulus being mounted in a carrier 14, FIG. 1, with freedom for movement in a first direction within the carrier, while the carrier itself is pivoted (24) in an outer housing 15, the carrier being free for movement in a second direction within the housing. The effect of normal drive of the rotor is to hold the parts in the FIG. 1 position while pumping continues, but in the event of drive reversal a pressure fluctuation causes the annulus to be displaced within the carrier and then the carrier to be displaced within the housing so as to bring the parts to substantially the mirror image of the FIG. 1 position allowing continued pumping in the same direction from inlet to outlet under reversed drive.
